Moving Timelapse
You know how to make a timelapse movie now, but how about one that moves?
In order to get this to work, you have to have a system that can move your camera precisely after each exposure. You want it to take a shot, move the camera a fraction and take another shot.
Timelapse Rail on location
Typically this is done along a straight rail system, that has a motorized bed that transports the camera along at precise intervals. I use a kit from Dynamic Perception
Timelapse Shooting
Calculations are similar to regular timelapse but now you have to factor in how far the camera is going to move through the clip.
Lets say your camera will move 5 feet. So those 240 frames (figuring a 10 second clip) will need to be divided over five feet. This will give you the distance that the camera needs to move after each exposure, over the time it takes to shoot 240 frames.
One thing to keep in mind is if something is close to the camera lens, say, a pillar, a tree, or a wall, etc. you will need to move the camera in small increments. Otherwise the end film will be choppy.
If the subject is farther away you can move the camera larger distances between shots. if you don't do this, you may not see that the camera is moving at all. Which would be a bunch of calculating for nothing.
